trying to see if anyone knows if the head for a f22b1 match up on an f22a1. seeing if a vtec head will work on f series block, with out going to h22?

umm, technically it will, with modifications, but it's going to cost you as I replied on the other thread about this.

Unless it's practically given to you, not worth it. I would go h22 even though it's a bit of money, or go nitrous instead (around $300-500 for a simple zex nitrous kit on eBay that'll do fine). Nitrous = about as expensive as the f22b1 head swap, more power, and eh, ya.
